Proteus™ Copolymer PP Natural shapes offer excellent chemical and corrosion resistance capabilities, improved resistance to stress cracking, ease of fabrication and welding and minimal centerline porosity. Due to these performance properties, Proteus™ Copolymer PP Natural is a favored solution for components in die cutting pads, fire truck water and foam tanks, orthotic and prosthetic devices and plating and anodizing process equipment. This grade is also FDA and NSF compliant.
